Ohmic Tube

An ohmic tube, also known as a transistor, is an electronic device that is widely used in electronics. It was discovered and manufactured by the German physicist Julius Eduard Lilly Ohm, hence the name ohmic tube.

The working principle of the ohmic tube is based on the triode structure. The ohmic tube species consists of three regions: the emitting region, the base region and the collector region. The emitting region provides electrons through an external voltage or current, the base region is used to control the flow of electrons, and the collector region receives the flow of electrons.

Specifically, when a positive voltage is applied between the emitting region and the base region, the emitting region generates a stream of electrons. This electron flow is controlled by the voltage in the base region. When a negative voltage is applied between the base and the collector region, an electron stream is formed to flow from the collector region. And when the voltage in the base region is altered, it will have an effect on the current flow in the collector region.

The main use of ohmic tube is to amplify and switch the current. It can change the amplitude of the output current in response to small changes in the input voltage. This current amplification characteristic makes it an important component in electronic equipment. Ohm tubes are widely used in a variety of electronic equipment such as radio, television, computers, telephones, and so on.

In the field of radio communication, ohmic tube is widely used in amplification circuits. It enhances the strength of radio signals so that they can be transmitted over long distances. Ohm tubes are also used in frequency converters and oscillators to generate and adjust high-frequency signals.

In the field of computers, ohmic tubes play a key role. In microprocessors, the switching characteristics of ohmic tubes enable high-speed calculations and complex logic operations. The small size and high integration of ohmic tubes allow modern computers to have high performance and efficiency, and enable smaller and lighter devices.

In addition, ohmic tubes are used in electronic devices such as monitors, cameras, and sound amplifiers. In audio amplifiers, ohmic tubes enhance the amplitude of the audio signal so that the audio can travel better. In monitors, ohmic tubes can control the flow of light so that images can be displayed.

In short, the ohmic tube is an important electronic device that realizes the functions of electronic devices by amplifying and controlling the current. It works on the principle of a triode structure, which controls the flow of electron streams with external voltages and currents. Ohm tubes are used in a wide variety of applications, including radio communications, computers, audio amplifiers, displays, and various other fields. As technology continues to develop, ohmic tubes will continue to be improved and utilized to drive the advancement of electronics. Types of Ohm Tubes
